Please consider this one carefully. K2 made a hip issue worse and caused my knees to feel painful/swollen where there was no knee issue before. I believe there are cheaper/more effective/less harmful ways to prevent/reverse calcification and/or get rid of calcium spurs etc. If needed at all, I argue that vit K1 is sufficient - our bodies do a stellar job of converting it to vit K2, regardless of gut flora. And I suggest vit D/magnesium deficiency is more likely than vit K. I personally found my bone/endocrine health improved most significantly once I stopped drinking tap water (even filtered). I now only drink bottled spring water and use bottled or filtered water for cooking (and some washing, e.g. face/hair) - chloramine is not fit for human consumption. Even without doing/taking anything else - not drinking tap water made a significant enough difference that I wholeheartedly advocate it as a must-try for anyone suffering any kind of health issue. Note that vit K needs vit D, copper, B5 (and calcium) - if already low, vit K will lower them further (along with things it antagonises, e.g. magnesium).

Don't be persuaded by the people who're pushing MK-7
This is the stuff our bodies manufacture.
This stuff improves blood circulation, clotting and reduces atherosclerosis, etc.
It even helps skin and dental health!
